Important Safety Notice
Proper service and repair is important to the safe, reliable operation of all AOC Company Equipment. The service procedures recommended by AOC and described in this service manual are effective methods of performing service operations. Some of these service operations require the use of tools specially designed for the purpose. The special tools should be used when and as recommended.
It is important to note that this manual contains various CAUTIONS and NOTICES which should be carefully read in order to minimize the risk of personal injury to service personnel. The possibility exists that improper service methods may damage the equipment. It is also important to understand that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. AOC could not possibly know, evaluate and advise the service trade of all conceivable ways in which service might be done or of the possible hazardous consequences of each way. Consequently, AOC has not undertaken any such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which is not recommended by AOC must first satisfy himself thoroughly that neither his safety nor the safe operation of the equipment will be jeopardized by the service method selected. Hereafter throughout this manual, AOC Company will be referred to as AOC.
WARNING
Use of substitute replacement parts, which do not have the same, specified safety characteristics, might create shock, fire, or other hazards.
Under no circumstances should the original design be modified or altered without written permission from AOC. AOC assumes no liability, express or implied, arising out of any unauthorized modification of design. Servicer assumes all liability.
FOR PRODUCTS CONTAINING LASER: DANGER-Invisible laser radiations when open AVOID DIRECT EXPOSURE TO BEAM. CAUTION-Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. CAUTION -The use of optical instruments with this product will increase eye hazard.
TO ENSURE THE CONTINUED RELIABILITY OF THIS PRODUCT, USE ONLY ORIGINAL MANUFACTURER'S REPLACEMENT PARTS, WHICH ARE LISTED WITH THEIR PART NUMBERS IN THE PARTS LIST SECTION OF THIS SERVICE MANUAL. Take care during handling the LCD module with backlight unit
-Must mount the module using mounting holes arranged in four corners.
-Do not press on the panel, edge of the frame strongly or electric shock as this will result in damage to the screen.
-Do not scratch or press on the panel with any sharp objects, such as pencil or pen as this may result in damage to the panel.
-Protect the module from the ESD as it may damage the electronic circuit (C-MOS).
-Make certain that treatment person’s body is grounded through wristband.
-Do not leave the module in high temperature and in areas of high humidity for a long time.

2.2 Setting Up to Watch Television
2.2.1 Getting Started
Your VIA-enabled HDTV has a built-in Setup App that plays when you turn on your TV for the first time. Follow the on-screen directions to easily setup your new HDTV.
1. Insert batteries into the remote control.
2. Connect the power cord to the power cord connector on your HDTV, and then plug the power cord into an AC wall socket.
3. Gather the devices your want to connect to your HDTV. Don’t connect them yet. We will help you do that in the Setup App.
4. Turn on your TV. The Setup App will automatically play and guide you thru the initial setup of your HDTV. Use the
arrow and OK buttons to navigate through the Setup App. During the setup process you will:
Connect to the Internet
Add your TV channels (unless you have a Cable/Satellite set-top box)
Connect your devices and set up your remote to control them.
6
2.2.2 Using your HDTV for the first time
Connecting to the Internet
Set up the Internet connection using the initial Setup App or the Network Menu in the HDTV Settings App. Your HDTV has 802.11n single-band wireless, so you can connect your TV to the Internet through your wireless home network. Or you can also connect to the Internet by plugging in an Ethernet cable from your Internet connection into the Ethernet port on your HDTV. A wired connection may provide a more consistent connection depending on the conditions in your home environment.
Select Input Source
Select the input source for your HDTV by pressing INPUT on the remote control or the side of your TV. Pressing this button will cycle you through the following options: TV, AV, Comp, HDMI-1, HDMI-2, HDMI-3, HDMI-4, and RGB. Turn on your device and you will see a picture on your HDTV. If there is no picture, make sure you have selected the correct input on your HDTV.
Note: If the selected device is RF connected, your HDTV must be in TV mode
and on either channel 3 or channel 4 matching the channel which has been selected on the back of the VCR, Cable Box, External TV Tuner or Satellite Receiver. Refer to Owner or User’s Manual of such equipment for details.
Watching a TV Program
Before you start watching TV, make sure that any Cable, Satellite or off-air antenna connections are secure. Also, verify that the power cord is plugged into a correctly grounded electrical outlet or surge protector.
1. Press the power button on the remote control. The small window on the bottom right hand side of the front bezel will light up white
2. Select the input to which your device is connected that provides TV programming (e.g. TV, HDMI, and COMP).
Note: You should be able to see a picture. If you do not, make sure that all of your HDTV connections are secure
and you have selected the correct video input source. Each press of INPUT on the remote control will cycle through the available inputs. Press the button until the input associated with the device you want to view is shown.
3. When using the TV input, press the channel buttons on the remote control to change the channel. The channel buttons will not work if you are watching a program using HDMI, Component, or AV inputs.
Note: If your HDTV is in TV mode, pressing CH+ and CH- will not work until a channel scan has been run. Note: You can use your HDTV Component input to accept A/V signal (Composite) from a source with A/V out,
please plug your video signal (yellow connector) into the Component input (green connector) and match up the audio connectors (R and L) for the sound. Expect to see a black/white video in the Component input, if it is selected by accident.
Viewing Digital TV Program Information
When the channel is changed an information header is shown over the picture for a few seconds. Press GUIDE to display more information about the program and schedule. Press INFO repeatedly to display additional information for that channel.

setting you created.
Backlight
The backlight level adjusts the lamp current and this affects the overall brilliance of the picture but does not affect the Brightness (black level) or Contrast (white level) of the picture.
Brightness
The brightness adjusts the black levels in the picture. If the brightness is too low you will not be able to see the detail in darker parts of the picture and if the brightness is too high the picture will look washed out.
Contrast
The contrast adjusts the white levels in the picture. If the contrast is too low the picture will look washed out and if the contrast is too high you will not be able to see any detail in the bright parts of a picture.
Color
Color adjusts the amount of color in the picture.
Tint
The tint adjusts the hue of the picture. The easiest way to set tint is to look at flesh tones and adjust for a realistic appearance. In most cases, the default middle position is correct. If people’s faces look too orange try reducing the
11
level of color first.
Sharpness
The sharpness adjustment adjusts the sharpness of the edges of elements in the picture. It does not produce detail that otherwise does not exist. This adjustment is helpful when viewing (Standard Definition) sources.
Size & Position

Choose from Off, Normal, Rich Color, Green/Flesh, and Green/Blue.• Adaptive Luma Large areas of brightness in the picture will result in a higher Average Picture Level (APL) and the overall picture will look too light. This feature will lower the APL to counteract this effect. Choose from Off, Low, Medium, Strong, or
Film Mode Choose from Off or Auto. When set to Off it will stay at 60 fps. When set to Auto, the TV will detect the cadence (for example at 24 frames/second for film, or normal video at 60 fps).
